Wow! Increases Bloodflow! Cleans vessels! This will give you a "niacin flush" if you are using niacin for the first time. After a few days of using it, you will barely notice it--but will probably be able to tell it's working. How do I know it works? For one example, it gives me red lips as it improves blood flow to my skin/facial area. My naturopath told me that in order to get the REAL effects from niacin, you have to use the flushing kind. Just don't start out with the 1000's! My son and I tried this, and it is a real experience! April 3, 2014
Great Product I could tell it was a quality product the first time I took it. January 8, 2012
These time released Niacin vitamins definitely do not help with flushing. My husband flushed so bad from these, we will not be buying this brand again. October 4, 2011
Wanna be a Roman candle? This product makes me flush like I'm on fire! Just one tablet and I'm the Pink Panther--hot and uncomfortable. I'm glad I got the Carlson No-Flush brand now that really works, even at twice the milligrams. February 26, 2010
